Brushed mota inozivikanwawo seDC mota kana kabhoni brashi mota.DC mota inowanzodaidzwa kunzi brushed DC mota.Iyo inotora ma mechanic commutation, iyo yekunze magineti pole haifambi uye iyo yemukati coil (armature) inofamba, uye commutator uye rotor coil inotenderera pamwechete., mabhurashi nemagineti haafambi, saka commutator nemabhurashi zvinokweshwa nekukweshwa kuti zvipedze kuchinjika kwekwazvino.
Zvakaipa zve brushed motors:
1. Mhepo dzinogadzirwa nemuchina wekuchinja dzinokonzeresa kupokana pakati peiyo commutator nebhurashi, kupindira kwemagetsi, ruzha uye hupenyu hupfupi.
2. Kusavimbika kwakashata uye kukundikana kwakawanda, kunoda kugara uchigadziriswa.
3. Pamusana pekuvapo kwemufambisi, inertia ye rotor inogumira, kukurumidza kukurumidza kunogumira, uye kushanda kwesimba kunobatwa.
Sezvo iine zvikanganiso zvakawanda, nei ichiri kushandiswa zvakanyanya, nekuti ine yakakwira torque, chimiro chiri nyore, kugadzirisa kuri nyore (kureva, kabhoni brashi kutsiva), uye yakachipa.
Brushless mota inonzi zvakare DC variable frequency mota (BLDC) mune mamwe minda.Iyo inotora magetsi commutation (Hall sensor), uye iyo coil (armature) haifambisi magineti pole.Panguva ino, magineti echigarire anogona kunge ari kunze kwecoil kana mukati mecoil., saka pane musiyano pakati pekunze rotor brushless mota uye yemukati rotor brushless mota.
Iyo brushless mota yekuvaka yakafanana neyechigarire magineti synchronous mota.
Nekudaro, imwe brushless mota haisi yakazara simba system, uye iyo brushless inofanirwa kudzorwa nebrashiless controller, kureva, ESC kuti iwane kuenderera mberi kwekushanda.
Chinonyatso sarudza kuita kwayo ndeye brushless yemagetsi gavhuna (kureva, iyo ESC).
Iine zvakanakira kushanda kwepamusoro, kushandiswa kwesimba shoma, ruzha rwakaderera, hupenyu hurefu, kuvimbika kwepamusoro, servo control, stepless frequency conversion speed regulation (kusvika pakumhanya kukuru), nezvimwe. Iduku zvikuru kupfuura brushed DC motokari.Kudzora kuri nyore kupfuura iyo asynchronous AC mota, uye yekutanga torque yakakura uye kuwanda kwehuwandu hwakasimba.
Iyo DC (brush) mota inogona kugadzirisa kumhanya nekugadzirisa voltage, kubatanidza kupikisa munhevedzano, uye kushandura mafaro, asi ndiyo inonyanya kupfava uye inonyanya kushandiswa kugadzirisa voltage.Parizvino, iko kushandiswa kukuru kwePWM yekumhanyisa mutemo, PWM irikuburikidza nekumhanya-mhanya kwekuchinja kuti uwane mutemo weDC Voltage, muchikamu chimwe chete, iyo nguva yeON iri kureba, iyo yakakwira avhareji yemagetsi, uye kureba iyo OFF nguva iri. , iyo yakaderera avhareji voltage iri.Zviri nyore chaizvo kugadzirisa.Chero bedzi iyo inoshandura kukurumidza kukurumidza zvakakwana, iyo harmonics yemagetsi grid ichava shoma, uye ikozvino ichave ichienderera mberi..
Stepper Motor - Vhura Loop Stepper Mota
(Open-loop) Stepper motors idzo dzakavhurika-loop dzinodzora mota dzinoshandura masaini emagetsi pulse kuita angular displacements, uye anoshandiswa zvakanyanya.
Muchiitiko chekusawedzerwa, kukurumidza uye kumira kwechinzvimbo chemotokari kunongoenderana nehuwandu uye nhamba yemapulisi echiratidzo chepulse, uye haisi kukanganiswa nekuchinja kwemutoro.Kana mutyairi wenhanho agamuchira chiratidzo chekurova, inotyaira mota inotsika kuti itenderere.A angled angle, inonzi "step angle", iyo inotenderera iyo inomhanya nhanho nhanho pane imwe nzira.
Iyo angular displacement inogona kudzorwa nekudzora huwandu hwemapulses, kuitira kuti uwane chinangwa chechokwadi chinzvimbo;panguva imwecheteyo, kukurumidza uye kukurumidza kwekutenderera kwemotokari kunogona kudzorwa nekudzora pulse frequency, kuitira kuti uwane chinangwa chekugadzirisa kukurumidza.
